boustrophedon

boustrophedon /n./ [from a Greek word for turning like an ox
while plowing] An ancient method of writing using alternate
left-to-right and right-to-left lines. This term is actually
philologists' techspeak and typesetters' jargon. Erudite hackers
use it for an optimization performed by some computer typesetting
software and moving-head printers. The adverbial form
`boustrophedonically' is also found (hackers purely love
constructions like this).
